Physics of the conceptual design of the ITER plasma control system

Jonathan Bryan Lister, Richard Pitts

The ITER plasma control system (PCS) will play a central role in enabling the experimental program to attempt to sustain DT plasmas with Q = 10 for several hundred seconds and also support research toward the development of steady-state operation in ITER. ...

Benchmark Of Fluid And Kinetic Simulations Of Type Iii Elming H-Mode On Tcv

Richard Pitts, Barbora Bruant Gulejová

Although the most complex currently available fluid-neutral Monte-Carlo plasma boundary code package, SOLPS, has been a major player in the ITER divertor design, it has not yet been systematically used for the study of kinetic phenomena such as ELM transie ...

ELM induced divertor heat loads on TCV

Richard Pitts, Jan Horacek, János Márki

Results are presented for heat loads at the TCV outer divertor target during ELMing H-mode using a fast IR camera. Benefitting from a recent surface cleaning of the entire first wall graphite armour, a comparison of the transient thermal response of freshl ...

SOLPS5 simulations of Type I ELMing H-mode at JET

Richard Pitts, Barbora Bruant Gulejová

This paper aims to contribute both to the ongoing process of scrape-off layer code-experiment and code-code benchmarking. Results are presented from SOLPS5 simulations of two high power JET H-modes with similar magnetic configuration, concentrating in the ...

Kinetic simulations of the parallel transport in the JET scrape-off layer

Richard Pitts

in this paper, we present kinetic simulation results of plasma parallel transport in the stationary and ELMy scrape-off (SOL) layer. We demonstrate that number of kinetic factors describing SOL are strongly nonuniform and evolve during the ELM. Power loads ...
